We experienced a case of lumbar disc herniation migrated to the posterior epidural space, combined with bladder bowel disturbance.
A 64-year-old man had lumbar pain, bilateral weakness in both legs, and bladder bowel disturbance. He was admitted to our hospital. Myelogram, CTM, and MRI showed a mass compressed epidural space at L1/2 level. We suspected lumbar disc herniation migrated to the posterior epidural space or epidural tumor.
After laminectomy at L1/2, a mass posteriorly compressed the dura, reaching in a stalk to the L1/2 space. Histopathological examination showed this mass to be a composed disc with inflammatory cell infiltration.
